Subgraph densities are relatively simple to calculate and have been found to provide interpretable features about the interactions of the system under study [1]}. For example, the density of triangles in a social network describes the clustering tendency of the individuals in the network; this value has been shown to be an important feature of international trade relations and political co-voting tendencies [2]}, [3]}, [4]}. In neuroimaging applications, the number of \(k\) -star configurations in functional connectivity networks of typically developing adults is significantly higher than expected at random [5]}, [6]}. Examples of subgraph configurations are given in Figure REF .
